A duct system in Lilburn cools through a long, humid season, breathes some of the heaviest pollen in the country and often runs through a crawlspace. This is what we actually find here, and what we check on every visit.
Spring in Lilburn turns cars yellow in a weekend, and the same pollen cloud settles into return ducts through every open window and door. The system stores it and redistributes it long after the trees finish, which is why indoor symptoms outlast the season for many families here.
A large share of Lilburn homes run their ductwork through a vented crawlspace that stays humid most of the year. Dust inside those ducts sits in moisture, joints sweat, insulation gets damp, and the musty smell that follows is a duct problem before it is anything else.
In a dry climate dust stays loose; in Gwinnett County it cakes. Moisture makes the dust inside ductwork cling and build in layers, so a Southeast system can look worse at five years than a desert system at ten - and a surface wipe at the registers does nothing for what is packed in the trunk.
Separated joints under a Lilburn house spill cooled air into the crawlspace all summer. The system runs longer, the floors can feel clammy from the humidity that follows the pressure change, and the fix is sealing and repair under the house rather than a larger AC.

Usually the attic ductwork: joints leaking cooled air, runs sagging between straps, or an undersized return starving the second floor. In Gwinnett County we trace the upstairs runs end to end on the inspection, and repair or sealing normally closes most of the gap.
